SSCMA Deployment on Espressif Chipsets

English | 简体中文

Introduction

The project provides examples of how to deploy models from SSCMA to Espressif chipsets. It is based on the ESP-IDF and TFLite-Micro.

Getting Started

Install ESP IDF

Follow instructions in this guide ESP-IDF - Get Started to setup the built toolchain used by SSCMA examples. Currently we're using the latest version v5.1.

Clone and Setup the Repository

1. Clone our repository.

   git clone https://github.com/Seeed-Studio/sscma-example-esp32

2. Go to sscma-example-esp32 folder.

   cd sscma-example-esp32

3. Fetch the submodules.

   git submodule update --init

Build and Run Examples

1. Go to examples folder and list all available examples.

   cd examples && \
   ls

2. Choose a <demo> and enter its folder.

   cd '<demo>'

3. Generate build config using ESP-IDF.

   Currently we develop and test on XIAO-ESP32S3 module.

   # set build target
   idf.py set-target esp32s3

   You can change a display driver, enable or disable a TFLite operator if it need using menuconfig.

   # change device or demo specific configuration
   idf.py menuconfig

4. Build the demo firmware.

   idf.py build

5. Flash the demo firmware to device and Run.

   To flash (the target serial port may vary depend on your operating system, please replace /dev/ttyACM0 with your device serial port).

   idf.py --port /dev/ttyACM0 flash
   

   Monitor the serial output.

   idf.py --port /dev/ttyACM0 monitor
   

Tip

• Use Ctrl+] to exit monitor.

• The previous two commands can be combined.

  idf.py --port /dev/ttyACM0 flash monitor

Supported Models and Performance
